In this episode, Mr. Feeny says that he does not fish. However, before a fishing trip in season 1, he helped Alan show Cory and Shawn how to use the fishing rod. Also, later on in the show, during his attempt at retirement, Mr. Feeny spends all of his time fishing.
Shawn gets mad at Cory for eating meat. In real life Rider Strong is a vegetarian.
Morgan needs $25 for school pictures; yet when she reaches into her father's wallet, she only pulls out one bill.
Shawn: My dear, sweet Cory. There's no shame. There's two types of people in this world: people like you, who always manage to get bye; and people like me, that were lucky enough to have people like you in their lives.
Cory: Mom, it was the weirdest thing. Last night I'm walking by the Gap; they got a monkey selling jeans.
Eric: I gave them that idea!
Cory: Well, next time you go out for a job, wear a diaper and smoke a cigar. People like that.
Cory: Oh, Dad. Keep your wallet open; I got pictures too.
Alan: What grade are you in?
Alan: We got enough of you.
Cory: So, now my future depends on a Bavarian named Ogner. Shawn warned me about this.
Eric: Hey, you hear that? I'm going to be responsible for the well-being of this family!
Cory: Bye-bye house.
Shawn: You're my friend and I'm gonna teach you how to be poor.
Cory: Would ya?
Shawn: Well, it's not gonna be easy. You come from a world of many pants.
Shawn: Oh, you had it easy, all right. You, with your breakfasts in the morning, your lunches in the afternoon, your dinners at night. Eaters! You're eaters!
Shawn: Wow; and to think, you were my only rich friend.
Cory: Comfortable; never rich.
Shawn: Indoor plumbing? Rich.
Eric: Hey, Dad; how great is this? I'm going to be working for you.
Amy: I'm glad you feel that way, Eric, because uh, we're going to have to tap into your college fund, for the down payment.
Eric: Hey, Dad; how great is this? You're going to be working for me.
Mr. Feeny: Might I suggest, for the sake of communal bliss, that you outfit yourselves with one of those two person sleeping bags that are currently on discount at Kimball's.
Alan: George, you rascal! How do you know about those?
Mr. Feeny: I go camping. I don't fish. You do the math.
Shawn: You sound sincere; but let me ask you one question. When was the last time you slept inside?
Cory: Last night.
Shawn: I can't work with you.
Mr. Feeny : I'm a teacher, not a heart surgeon.
William Daniels played a heart surgeon on the hit drama, St. Elsewhere, which ran from 1982 until 1988.
